The movement encourages women to go topless in public, believing society has made people think exposing their breasts is taboo, and now TaTa Top designers Robyn Graves and Michelle Lytle have created a skin-coloured bikini which has lifelike nipples to give the illusion of being bare-chested.

The saucy swimwear comes in three skin tones: Nude, medium and dark tone, allowing anyone to wear the bikini top and support the cause.

The cost per top is $28, and every $5 of each sale will go towards a breast cancer research foundation.

Graves and Lytle mission is to "desexualise" the nipple, writing on their website "the only excitement that comes from seeing breasts is that you are conditioned to think that they are something special, something to be protected and kept hidden."
